Atul: Heavy rains expected in Goa next 2 days. UAC forms off Goa coast, and an upper air trough runs thru Goa. Would expect heavier rains on Tues/Wed in interior Goa. Would expect around 30 mms next 2 days in Panjim.

Sir is it so are the rains increaseing in mumbai by saturday on sunday.n when is monsoon withdrawing from mumbai.are there any chance of rain in navratri in mumbai after the withdrawal of monsoon from mumbai khyati pandit

@K.P , rains increasing, is just a query at the moment, which i have put before rajesh sir ,because i wanted to know his view, and i said it because' it looks like as though the UAC from bay will enter Maharashtra and might delay the monsoon withdrawal in MUMBAI AND KONKAN.So altogether it's just a ?...

Rajeshbhai: Indeed as mentioned by you in comments on 16th night, incessant rains lashed all parts of Goa since after midnight. Panaji recorded 21 mm in 4 hrs from 2:30 am to 6:30 am. Skies heavily overcast today, but light drizzle only. Reports of some areas receiving heavy rain spells. Let"s see what the evening and night of 17th have in store!

khati/Vinod/sam: lets see, i am working out on the next forecast 9beyond thursday) now...shall put it up, at least in brief..if the SWM withdrawas by end of ept, then there could be no rains during Navratri. But will be more specific in article

correct today early morning Navi Mumbai had heaviest of rains ever seen this year. Just like june-july rain without thunders. Guess it would have dumped 100mm in less than hour. It seems this sept is probably wettest ever for Mumbai. Places like Badlapur (mentioned by Abhijit, also came in news) received 180-200mm in few hours is something record breaking. Usually as per tradition since last many years Mumbai always gets rains during janmasthami, ganesh immersion, navrathri and probably few years it used extend till Diwali (2011).

sam/vinod/kp/sset/Moshin..and all: Why don't you confirm for our vagarians meeting on the 28th of Sept. The meeting is arrange at Panvel.Please make sure you attend to have better inter action and understanding with each other...you can confirm on blog comments also..after all, blog readers are a bigger vagarians group !

Mumbai radar continues to be down. On a day when millions will be on the road. Not sure if IMD folks at the local weather station even monitor the radar, else they would have seen it not functioning on the site.

Rained in few places of south Chennai yday evening..hot and humid now..expecting showers today evening..btw, no sign of wind reversal till month end and circulation may form near AP coast in the last week of Sep..

rajesh sir,suddenly in eastern outskirt in mumbai along with navi mumbai started heavy thunder with lightning and cloud brusting..it is effect of low or natural withdrawal phenomenon.what abt upcoming low its hit mumbai or miss it..ur view on that...

Rain, lightning and thunder have commenced at Juhu around 15 minutes back. The squall preceding the storm wasn't much here as compared to what was reported from Panvel. There are lots of people on the road at Juhu and some Ganeshas are still reaching the beach for Visarjan

it seems monsoon axis has overstayed in central india- MAHA receiving nonstop rains. Will it shift down south so that cities like BANG,MYS,TN,AP can observe thunders and of-course get only SEPT rains as other months was too dry. By the way NAVI MUMBAI after midnight storm, again at 4am early morning got torrential non-stop rains.

Dear Rajesh, As pointed out by you Chennai and major parts of its suburbs are getting TS daily beginning from 1700 hrs IST to mid night and sometimes beyond. These all are thunder cells of Cumulonimbus clouds developing in the after noon. During evening the low level Nimbostratus clouds, thick enough to hide sun with threatening grey color is spreading out of matured Cumulonimbus clouds and engulfing the sky from West to East and giving rainfall ranging from 10-40 mm. The thunderstorm with rain lasts for 30 min to a maximum of 60 min with gale wind force. These sort of rainfall during September month for this region is common, but its persistence in time [more than 4 days] and in space [Major parts of North & NW TN]is unusual.

Dear SSETWe are all weather enthusiasts who want to know more so i though of sharing this information. Interior peninsular India has received surplus rains this year. Refer to the following link for 2013 south west monsoon rainfall so farhttp://www.imd.gov.in/section/nhac/dynamic/Monsoon_frame.htmAlso peninsular interior gets rain outside the official south west monsoon months of June through September. For example for Mysore the rainiest month is October and the second rainiest month is May so when you look at just the rain that falls in the official south west monsoon months you will not get the complete picture. Refer to the following link for mysore's average monthly rainfall http://www.imd.gov.in/section/climate/extreme/mysuru2.htm . October rain is 16 cm and May rain is 14 cm.

Also comparing Konkan and interior peninsular rainfall makes no sense, they have different climates with regard to rain. Konkan and coastal Karnataka comparison makes a lot more sense.

One final pointVariations within a region are quite common. So if one city has received less rainfall that does not mean the entire area is witnessing drought.For example this year Delhi has received excellent rain. Refer to http://www.cpc.ncep.noaa.gov/products/global_monitoring/precipitation/sn42182_1yr.gif

but the group(Harayana) under which it is put by the met department has received 27% less rainfall.

By the way here is the link for Bangalore rain for that last one year.http://www.cpc.ncep.noaa.gov/products/global_monitoring/precipitation/sn43295_1yr.gif

Diwediji myself completely disagree. I still maintain same view interiors of KAR/Rayalseema/many areas of TN are most driest places. september few days of rains over these places was due to low over TN - again not great rain compared to vidarbha lows. If you notice entire monsoon these areas did not receive any rain. Kind of mercy low over TN in month of September may not repeat every year. In fact if we compare interiors of KAR with Marathwada (not konkan/vidarbha/madya maha) still it is very less rain. Figures you are showing for mysore was valid 10years back now whole climate has changed and become arid. Infact last 3-4 years shows among major cities BANG/MYS receive lowest of rains. In fact these places have become unreliable for water (god knows how people and industries grow)and proximity to Rayalaseema is another fear advancing aridity...
